Problems solved by technology
[0002] During the printing process, the roll paper needs to be output first. The output paper is generally a little loose, which cannot meet the tension requirements, which is not conducive to subsequent processes such as printing, or the output paper is too tight due to the failure of mechanical parts. Stretch, prone to breakage or breakage, is also not conducive to printing, and the existing device can not achieve the function of automatic adjustment

Description
technical field [0001] The invention relates to the technical field of printing, in particular to an automatic adjustment and control device for paper tension of printing equipment. Background technique [0002] During the printing process, the roll paper needs to be output first. The output paper is generally a little loose, which cannot meet the tension requirements, which is not conducive to subsequent processes such as printing, or the output paper is too tight due to the failure of mechanical parts. Stretch, prone to damage or breakage, is also not conducive to printing, and the existing device can not achieve the function of automatic adjustment. Contents of the invention [0003] The object of the present invention is to provide an automatic adjustment and control device for paper tension in printing equipment, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provid...
